🧬 New Feature on MADAI LABS: Y-DNA Haplogroup Predictor
We have added a Y-DNA haplogroup prediction tool to the platform.
After uploading your raw data, the system analyzes your Y-chromosome SNPs and predicts the most likely haplogroup and subclades.
How it works
Safety Mode (default)
Used especially for autosomal raw data uploads.
• A clade is assigned only if at least 2 positive SNPs support it.
• If a deeper branch has only 1 positive SNP, the system assigns the nearest clade with 2 confirmed SNPs.
This prevents incorrect deep predictions caused by false SNP calls.
Manual verification
After the upload, we also review results using Fast Mode.
Fast Mode accepts ≥1 positive SNP, allowing deeper branches to appear.
We manually inspect these cases to determine whether:
• a false call occurred
• or a deeper plausible subclade exists.
Interactive SNP tree
The results include a phylogenetic tree showing:
• all relevant SNP branches
• positive and negative markers
• possible downstream subclades
• haplogroup formation ages
This allows users to visually explore their Y-DNA lineage and see where their sample fits in the tree.
